A traditional Klingon dish, among the best-known items of Klingon cuisine after gagh, and a childhood favourite of Worf that his human foster mother learned to cook.
Rokeg blood pie is a Klingon speciality served at feasts and on days of celebration. Like much Klingon food it is strongly flavoured and unappealing to most other species.
It is first seen in the Next Generation episode A Matter of Honor, among the dishes William Riker samples before his exchange posting on the Klingon ship Pagh. In Family, Worf's adoptive mother Helena Rozhenko recalls mastering the recipe when he was a boy on Earth, a small sign of how hard his human parents worked to honour his heritage.
In the Voyager episode Day of Honor, Neelix offers the pie to B'Elanna Torres to mark the Klingon holiday, though she is in no mood to observe it.
